This article visualizes L1 & L2 Regularization, with Cross Entropy Loss as the base loss function. Moreover, the Visualization shows how L1 & L2 Regularization could affect the original surface of cross entropy loss. Although the concept is not difficult, the visualization do make understanding of L1 & L2 regularization easier. For example why L1-reg often leads to sparse model. Above all, the visualization itself is indeedly beautiful.
